No full textThe functional communication of neurons in cortical networks underlies higher cognitive processes. Yet, little is known about the organization of the single neuron network or its relationship to the synchronization processes that are essential for its formation. Here, we show that the functional single neuron network of three fronto-parietal areas during active behavior of macaque monkeys is highly complex. The network was closely connected (small-world) and consisted of functional modules spanning these areas. Surprisingly, the importance of different neurons to the network was highly heterogeneous with a small number of neurons contributing strongly to the network function (hubs), which were in turn strongly inter-connected (rich-club). Examination of the network synchronization revealed that the identified rich-club consisted of neurons that were synchronized in the beta or low frequency range, whereas other neurons were mostly non-oscillatory synchronized. Therefore, oscillatory synchrony may be a central communication mechanism for highly organized functional spiking networks

Sandia National Laboratories results for the 2010 criticality accident dosimetry exercise, at the CALIBAN reactor, CEA Valduc France.
No full textThis document describes the personal nuclear accident dosimeter (PNAD) used by Sandia National Laboratories (SNL) and presents PNAD dosimetry results obtained during the Nuclear Accident Dosimeter Intercomparison Study held 20-23 September, 2010, at CEA Valduc, France. SNL PNADs were exposed in two separate irradiations from the CALIBAN reactor. Biases for reported neutron doses ranged from -15% to +0.4% with an average bias of -7.7%. PNADs were also exposed on the back side of phantoms to assess orientation effects
Impact of switching to the ICRP-74 neutron flux-to-dose equivalent rate conversion factors at the Sandia National Laboratory Building 818 Neutron Source Range.
No full textSandia National Laboratories (SNL) maintains a neutron calibration facility which supports the calibration, maintenance, and repair of Radiation Protection Instruments. The SNL neutron reference fields are calibrated using the following methodology: Fluence rate is initially established by calculation using the NIST traceable source emission rate (decay corrected). Correction factors for the effects of room return or scatter, and source anisotropy are then developed by using a suitable radiation transport code to model the geometry of the facility. The conventionally true neutron dose rates are then determined using the appropriate fluence-todose equivalent conversion coefficients at several reference positions. This report describes the impact on calculated neutron dose rates of switching from NCRP-38 to CRP-74 neutron flux-todose equivalent rate conversion factors. This switch is driven by recent changes to dosimetry requirements addressed in 10 CFR 835 (Occupational Radiation Protection)
Entführung eines „Mündels des Gerichts“ (ward of court) nach Deutschland
No full textBei der Anwendung des Haager Kindesentführungs-Übereinkommens ist darauf zu achten, dass ein Sorgerecht, das durch Entführung verletzt sein muss, bereits vor der Entführung bestanden haben muss. Es genügt also nicht, wenn ein englisches Gericht erst nach der Entführung das entführte Kind zu einem „ward of court“ macht. Dann ist die Entführung nicht rechtswidrig. Dies wird anlässlich einer Entscheidung des OLG München erörtert und klargestellt
Dorıs Lessıng'in mara and dann: An adventure ve the story of general Dann and Mara's daughter, grıot and the snow dog adlı eserlerınde antroposen çağının betimlemesi
No full textAntroposen, yirmi birinci yüzyılda büyük bir endişe kaynağıdır. İnsanın doğaya müdahalesini vurgular ve insanın canlı ve cansız varlıkları nasıl tahrip ettiğini ve bu müdahale nedeniyle ne gibi sonuçlar doğurabileceğini açıklar. Bir insanın müdahalesiyle yaklaşan felaketlerin imajını yaratma konusunda tutkulu olan Doris Lessing, Antroposen'in öncü yazarlarından biridir. Mara ve Dann: Bir Macera ve devamı olan The Story of General Dann ve Mara's Daughter, Griot ve The Snow Dog, eserlerinde kıyamet sonrası dünyanın yakın gelecekteki temsilcileridir. Her iki romanda da olay örgüsü uzak bir gelecekte geçiyor ve romanlardaki karakterler atalarının yaptığı hatalardan dolayı acı çekiyor. Bu çalışma, Antroposen'in romanlar üzerinden nasıl anlatıldığını, insan üzerindeki etkilerinin neler olduğunu ortaya koymayı amaçlamaktadır. Romanlar boyunca yazarın, insanların doğaya karşı tepkilerini nasıl kontrol edeceklerini öğrenene kadar hatalarından acı çekmeye devam edeceğini bize göstermeyi başardığı açıktır.The Anthropocene is a major concern in the twenty-first century. It highlights the human interference to nature and clarifies how human beings destroy the living and non-living things and what consequences can generate due to this interference. Doris Lessing, who is passionate about creating an image of the forthcoming disasters because of the intervention of a human, is one of the pioneer authors of the Anthropocene. In her works, Mara and Dann: An Adventure and its sequel The Story of General Dann and Mara's Daughter, Griot and The Snow Dog are the representatives of the post-apocalyptic world in the near future. Plots in both novels are set in the distant future and the characters in the novels suffer from the mistakes made by their ancestors. This study aims at demonstrating how the Anthropocene is described through the novels, what effects demonstrate on humanity. Throughout the novels, it is obvious that the author has managed to exhibit us that human beings will continue to suffer from their mistakes until they learn how to control their reactions towards nature
'Alternative' methods of coping: tattooing and humour as non-traditional methods of emotional expression
No full textMuch research has explored ‘traditional’ coping mechanisms individuals use to manage their own mental wellbeing. For example, websites which offer advice to young people (YP) on how to manage their own depression have discussed the benefits of physical exercise and healthy eating (e.g. Helpguide, 2014; KidsHealth, 2014; WebMD, 2014). Similarly, much research has explored the benefits of social support for positive mental health outcomes in YP (Rothon, Goodwin and Stansfield, 2012). However, there has been less of a focus on non-traditional, and often implicit strategies that YP employ in order to make sense of, discuss and manage emotions. This paper will review these non-traditional methods of expression that are particularly relevant to YP, with a specific focus on humour and tattooing. Although unrelated, they both differently provide YP with an ‘appropriate’ avenue to construct, make sense of and deal with difficult emotional experiences that occur in some YPs lives. Previous work on tattooing conceptualises it as being associated with negative mental health (Carroll et al, 2002; Brooks et al, 2003). However, with the popularity of tattooing in YP rising, tattoos are being used as a strategy to materially demonstrate what they have overcome, and as a symbol for strength (Way, 2013; Anderson, 2014). In comparison, humour is more of a discursive strategy enabling YP to reframe their distress and communicate it to others in a way that they feel comfortable (Plancherel and Monique, 1995). Similarly, professionals working with YP use humour as a method to communicate and regulate their own negative emotions (Gilgun and Sharma, 2013). This paper is a holistic review of both the literature and the media, exploring how YP negotiate understandings of emotion with particular relevance to humour and tattooing
Representing the (othered) other: a qualitative exploration of othered positionings in RuPaul's Drag Race
No full textContext/Aims: The success of RuPaul’s Drag Race (RPDG) has not gone unnoticed within the media - it has not long finished it’s ninth season, and continues to showcase an array of drag queens, tackling identity issues such as gender and sexuality (Gonzalez & Cavazos, 2016). Using RPDG as the focus, we argue that the drag queens negotiate multiple positionings in regard to being ‘othered’, and this intersectional lens is necessary in understanding these negotiations.
Method: Paying attention to the three most recent seasons (7-9, 2015-2017), we use an intersectionally-informed discourse analysis to explore the various ways that the queens are ‘othered’ within the show.
Findings: The discourses that emerge from the show function as a cultural, social, and historical lens for which drag queens are understood in today’s society. The discussions around gender, trans, race, and sexuality simultaneously conform to and resist against heteronormative and cisnormative identities.
Conclusion: In conclusion, we argue that it is how the drag queens navigate these multiple positionings that is important for understanding ‘othered’ identities
A Novel Concept for Home Healthcare Operations Using Electric Home Delivery Vehicles
No full textHealthcare systems worldwide rely heavily on the efficient allocation of caregivers in home- based care. Despite this, to this day, the majority of home healthcare (HHC) organisations plan their operations manually, an extremely time-consuming and labour-intensive task yielding sub-optimal solutions. Research efforts in the operations research (OR) field have extensively studied said problem under the HHC routing and scheduling problem (HHCRSP). However, the separate consideration of the planning of caregivers and re- sources required at visits are considered a relevant gap in the literature, as real-world organisations must plan both simultaneously.As a solution toward bridging this gap, this paper proposes the introduction of home de- livery vehicles (HDVs) to support HHC operations, in which the vehicles deliver resources required at patient visits in time for consultation. A mathematical formulation consider- ing the routing, scheduling, and synchronisation of caregivers and vehicles is presented, in which partial battery charging alongside hard visit and working time windows are key characteristics. A genetic algorithm (GA) is further developed to solve the proposed for- mulation, which is proven to perform efficiently in benchmark instances for the vehicle routing problem (VRP). Simulations were run on data generated synthetically by a sta- tistical model recreating the HHC needs of the London Borough of Islington. The results highlight the potential benefits of adopting such technology, resulting in an average re- duction of the required medical resources of 49.94% and a 19.23% reduction in costs with respect to standard operations using the same number of resources.Overall, the most economical operating strategy for a HHC organisation was identified to be the purchase of a number of resources equal to the number of visits requiring said re- sources. Such an approach was found to decrease the costs per visit by 1.26% with respect to HDVs. The marginal amount, however, is expected to be diminished in the coming years due to factors not captured in the analysis such as the higher scalability of HDVs and their resulting potential to meet the anticipated growth in demand for HHC, the ex- pected decrease in the price of electric vehicle technology, the economic incentives offered to adopt said technologies, and the potential collaboration between caregivers and HDVs. These, alongside extensions to the proposed model such as non-linear battery charging, are proposed as future research avenues.Mechanical Engineering | Multi-Machine Engineerin
